Chapter mission types

[Phalangitis]

Hi to all,
I am having a small problem and i woud appreciate greatly ant help please.I am trying to create new missions and from what i see there is one db table called mission types.Those missions are then take a scripted form in campaigns/script folder. For example a mission type in db is CAPTURE_REGIONS. This is "translated" to mission scripts as : "CONTROL_N_REGIONS_INCLUDING" . So there must be somewhere a pool of commands which is used for the scripted missions. I searched the lib (library) folder with no luck. Anyone knows where they are located?
I ask because scripted missions lack immagination and variety while in db i see many kind of missions like RAID_REGION for example.So i am guessing that the appropriate scripting commands must be "hiding" somewhere.
THanks in advance for anyone that will bother to help.

On top of that i would like to add another question.
Is it possible to add as reward instead of just money other payloads with a fixed time of as well?If yes with what syntax?
i tried varius syntaxes with valid-vanilla payloads but none seem to work.
Another alternative is this: The completition of a mission to fire a specific event which in turn will have an effect in the faction.
Thanks

EDIT If i find the solutions myself i promise to let you guys know.Cheers.
